"Marge vs. the Monorail" has been widely praised by fans and critics and is generally considered one of the best of the entire series. Writer Conan O'Brien has claimed that, of the Simpsons episodes that he wrote, this was his favorite. Leonard Nimoy's unexpected guest appearance was also widely praised. Despite this, the episode attracted some criticism when it was first aired due to the somewhat abstract and less situational nature of the plot, particularly from voice actor Yeardley Smith who in 1995 described the episode as "truly one of our worst".
